A torsion damping device includes a damper plate, a hub and a guide ring, all mounted coaxially with each other, together with a draw ring and a contact ring. A resilient gripping spring associated with the draw ring is, with the latter, confined axially between the contact ring and the damper plate, by virtue of an axial protuberance which is fixed with respect to at least one of the damper plate and contact ring. The draw ring engages on one of the two elements comprising the damper plate and the contact ring under the influence of the resilient gripping spring the latter engaging on the other one of these two elements.
